Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an identity confirmation device which can be used, for example, in a hospital to confirm correspondence between a patient and a therapeutic drug used for the patient.

[0002]

2. Description of the Related Art In hospitals, there have been occasional medical mistakes such as mistaken injection liquids used for patients or mistaken charts and mistaken treatments such as surgery. Such medical mistakes are a life-threatening problem for patients and should never be caused. In order to prevent such mistakes, the following system may be used. This system is a system in which a patient, an injection solution, and the like are identified by a barcode. The patient is equipped with a wristband having a patient code printed as a bar code, and the patient code is used to identify the patient. In addition, the injection liquid, medicine, etc., should have a bar code that identifies them.

A code reader for reading the above bar code is provided and is connected to a personal computer. In this personal computer, each patient code and bar code attached to medicines, medical records, etc. are registered. In addition, the above personal computer,
Medical record data for each patient is also stored so that the treatment or drug required for that patient can be specified.

When injecting a patient, for example, a doctor or a nurse causes the code reader to read the patient code attached to the wristband of the patient and inputs the code into the personal computer. On the other hand, the barcode of the injection solution container is also read by the personal computer by the code reader. The personal computer compares the code input from the wristband with the code input from the injection solution container, determines whether the injection solution should be used for the patient, and displays the result. For example, if the injection liquid is prepared by mistake, a message indicating that the injection liquid should not be used is displayed on the display of the personal computer.

[0005]

In such a system, a personal computer connected to the code reader must be installed in the patient's room or the personal computer must be brought in from the outside. In order to install a personal computer in every room, space and equipment are needed, so it costs money. However, there is a problem in that it is time-consuming to bring a personal computer into a hospital room whenever something needs to be done.

It is also conceivable that the patient data and the codes such as medicines stored in the personal computer are stored in a server (not shown) and only the code reader is brought into each hospital room. However, in that case, a communication line is required for transmitting the data read from each hospital room, operating room, etc. to the server and transmitting the judgment result of the server to the hospital room. In addition, since there is a possibility that the medical device will be affected in the hospital, it is difficult to wirelessly connect the server and the code reader, and proper wiring work is required. It would be expensive to prepare such a communication line. An object of the present invention is to realize, for example, at low cost a system that prevents a patient from mistaking a patient or a wrong drug in a hospital.

[0009]

1 and 2 show an embodiment of the present invention. The external appearance of the identity confirmation apparatus of this embodiment is shown in FIG. 1. This apparatus includes a pen-shaped apparatus body 1 and a clip 2. A reading window 3 is provided on one end face, a display lamp 4 is provided at the opposite end, and a reading start button 5 is provided at the tip thereof.
A reset button 6 is provided on the side surface of the. The inside of such an identity verification device is shown in FIG. That is, the data reading unit 7 corresponding to the reading window 3, the processing unit 8 connected to the data reading unit 7, and the first storage unit 9 and the second storage unit 10 connected to the processing unit 8 are provided. Further, the processing section 8 also includes a reading start button 5 for inputting a reading start signal, a reset button 6 for inputting a reset signal, and a display lamp 4 which is an output means of the present invention for outputting the processing result of the processing section 8. It is connected.

Next, the function of each unit will be described. When the reset button 6 is pressed, it outputs a reset signal to the processing unit 8. The processing unit 8
When this reset signal is input, the first and second
The data stored in the storage units 9 and 10 are erased at once. That is, the reset button 6 and the processing unit 8 constitute the reset means of the present invention.

When the reading start button 5 is pressed, it outputs a reading start signal to the processing section 8. The processing unit 8 to which the reading start signal is input operates the data reading unit 7, reads a barcode or the like through the display window 3, and inputs the data to the processing unit 8.
The data reading unit 7 has the same function as a normal bar code reader. Then, the data reading means 7 reads the bar code when reading the bar code.
It does not matter whether it is a type of scanning a bar code on the barcode or a type of scanning while still.

Further, the processing section 8 stores the input data in the first storage section 9 when the data is not stored in the first storage section 9, and the data is stored in the first storage section 9. If it is, the second storage unit 10 has a function of storing the data. When new data is input to the processing unit 8 and the data is already stored in the second storage unit 10, the data is erased and the new data is stored in the second storage unit 10. In this way, when the data is stored in both the first storage unit 9 and the second storage unit 10, after that, the data stored in both storage units 9 and 10 are compared, and it is determined whether or not they are the same data. . as a result,
If the two are the same, turn on the green indicator lamp 4,
If they do not match, red is lit. That is, the display lamp 4 corresponds to the output means of the present invention that outputs the determination result of the processing unit 8.

A method of confirming an injection solution using this device in a hospital will be described below. However, as a premise of using this device, it is necessary to attach the patient code to all the items used for the patient, such as the wristband of the patient, the patient's chart, injection solution, and other medicines. Then, press the reset button 6 to push the first and second
The data in the storage units 9 and 10 are erased. Next, while pressing the reading start button 5, the bar code of the wrist band of the patient is read by tracing the bar code on the reading window 3 in FIG. The processing unit 8 confirms that no data is stored in the first storage unit 9 and stores the input patient code in the first storage unit 9.

Similarly, the bar code of the injection solution container is read. Since the processing unit 8 stores the data in the first storage unit 9, the barcode of the injection solution container is stored in the second storage unit 1.
Store to 0. Then, when data is input to both storage units, the processing unit 8 compares the two. The data stored in the first storage unit 9, that is, the patient code and the second code
When the data stored in the storage unit 10 matches, the indicator lamp 4 is lit in green, and if they do not match, red is lit. If the green lamp is on, the injection is for that patient and can be used. If you make a mistake in the injection solution,
The red lamp tells you this so you don't make the wrong injection.

Further, when confirming the medicine to be taken by the same patient, the barcode attached to the medicine case is read while pressing the reading start button 5. Processing unit 8
Confirms that data is stored in the first storage unit 9. Further, since the barcode of the injection solution container is stored in the second storage unit 10, the barcode of the medicine case newly input after erasing this data is used as the second code.
It is stored in the storage unit 10. Next, the data stored in the first storage unit 9, that is, the patient code, and the second storage unit 1
The identity is judged by comparing the data stored in 0, that is, the bar code of the medicine case. If they match, the indicator lamp 4 lights up in green, indicating that the drug belongs to the patient. On the other hand, if they do not match, the processing unit 8 lights up red, which indicates that the medicine is wrong.

As described above, once the patient code is read, the read data is compared with the data stored in the first storage section 9 one after another until the reset button 6 is pressed. And the identity can be determined. And when confirming about another patient, the said reset button 6 is pushed and the 1st, 2nd memory | storage part 9,1 is pushed.
By deleting the data stored in 0, the reference data can be newly stored in the first storage unit 9.
Therefore, the identity can be determined based on the data stored in the first storage unit 9.

Since the identity confirmation device of the above embodiment can confirm the identity only by the device, it is necessary to connect a data reading device such as a bar code reader to a personal computer or a server as in the conventional case. Absent. Therefore, there is no need to carry a personal computer and the like, and it is not necessary to provide a communication line for connecting the server and the data reading device. Since the cost of equipment including communication lines is not required, it is possible to prevent the patient and the medicine from being mistaken for each other at an overwhelmingly low cost as compared with the conventional hand-held robot.

In the above-mentioned identity confirmation device, the display lamp 4 lights up a different color according to the result of determination of identity, but the display method is not limited to this. For example, the lamp may be turned on only when the identity is confirmed, or conversely, the lamp may be turned on only when the two are not the same. Further, not only the lamp but also an alarm buzzer that is issued when they are not the same can be considered as the result output means. Further, although the above bar code can be directly printed on a drug container or the like, if a sticker or tag on which a patient code is printed is prepared and used, it can be easily attached to any object.

In the above-described embodiment, an example in which the identity confirmation device of the present invention is used in order to prevent mistaking of patients, medicines, etc. in a hospital has been described. This is useful when it is necessary to confirm the identity with a certain standard. For example, it is possible to confirm whether different items are mixed in a place where a large number of the same products should be lined up, such as a warehouse. Also in this case, it is possible to compare the code read first and the code of each individual product read thereafter, and output the result. When a foreign substance is mixed, the code of the foreign substance does not match the code read at the beginning, so an alarm sounds and the foreign substance can be easily found.

In the above embodiment, the bar code is used as the data to be read by the identity verification device, but this is not limited to the bar code. Data reading unit 7
It is conceivable that all codes that can be optically read by, or those that can output an electronic signal such as an IC chip. For example, when the IC chip stores a signal that identifies each patient, the data reading unit 7 must have a function of receiving a signal transmitted from the IC chip.

[0021]

According to the first to third inventions, the identity of a person or an article can be confirmed by an inexpensive device. In particular, since the confirmation process is completed only by the identity confirmation device of the present invention, a communication line for connecting to a personal computer is unnecessary, and the cost can be reduced accordingly. Also, not only wired communication but also wireless communication is not required, so it can be used safely in places such as hospitals where the influence of electromagnetic waves is disliked.
